the median weekly earnings for american workers in 1990 was $412 and in 1999 it was $549. Calculate the average rate of change b

mina [271]

The rate of change between 1990 and 1999 is 15.22

Step-by-step explanation:

The rate of change in this case is given by change in quantity divided by change in time

So,

$Rate\ of\ change = \frac{Increase\ in\ money}{Increase\ in\ time}\\=\frac{549-412}{1999-1990}\\=\frac{137}{9}\\=15.22$

Hence,

The rate of change between 1990 and 1999 is 15.22

Answer:

That would be a histogram.

Step-by-step explanation:

Well it wont be a line graph because the data given is not a function. Also a bar graph shows categorical data which is different from a histogram because histogram shows numerical data. Also bar graph uses graphic presentation to compare different categories of data while a histogram shows frequencies of numerical data. Since our given data is a numerical data as well as the same kind of data we would therefore use a histogram.
